Safety at the Limit Tires for Performance-Tuned Cars 2 CASE STUDY ULTRA HIGH PERFORMANCE Safety at the limit Tires for performance-tuned cars 2 CASE STUDY ULTRA HIGH PERFORMANCE For the world’s fastest cars Ultra-ultra high performance (U-UHP) tires can be relied upon to maintain optimum performance levels at speeds of 360 km/h and above. A whole department at Continental is dedicated to developing bespoke tires for performance-modified vehicles from renown-ed manufacturers and brand tuners. For those occasions when a high-end standard production car no longer cuts the mustard, an individually tuned model is the obvi- ous answer. Tuning specialists give customers something special. Not by adding individual tuning components to elevate a car above the masses, but by creating overall concepts tailored to the driver and featuring a finely balanced choreography of Developing these tires for the tuning sector is one of the most A tuned Porsche 911 Turbo S by edo competition set a details with exceptional performance as their aim. challenging jobs in the business. For example, while a Mercedes record-breaking speed of 341 km/h on ultra-ultra high “We see tuning companies as specialist manufacturers and SL 500 leaves the factory with an output of 455 hp, the tuned performance tires from Continental at the proving refiners,” says Henry Siemons, who heads up the Tuning variant offered by Brabus produces 850 hp.

For this breed of vehicle you instead of the standard 450 hp. This is the sort of performance need tires that offer unbeatable dynamic performance and that can only be transferred safely onto the road by tires that safety – at speeds of up to 400 km/h.” offer the ultimate in performance. CASE STUDY ULTRA HIGH PERFORMANCE 3 Pushing performance skywards The increase in performance is also reflected in top speeds: U-UHP and tuning: a growth market Where series-produced models are electronically limited to 250 km/h, the tuned versions are largely capped at 300 km/h. Sales in the U-UHP and tuning segment are experiencing uninterrupted global growth. In Europe, sales of 19-inch tires are But not all of these hyper-powerful models are fitted with forecast to exceed 4,500,000 units. And the outlook is also promising in the USA, Russia and China. speed governors. A Brabus-tuned roadster based on the Mercedes S 600 can hit a maximum 327 km/h, while specialist Porsche tuners 9ff offer 911s that can crack the 380-km/h mark on a test track.

Among the elite specialists who fit their modified cars with Continental tires are Abt, AC Schnitzer, Arden, Brabus, 2014 2015 2016 2017 2018 2019 2020 Heico, Lorinser, edo competition and TechArt, to name just some. At Continental these tuning companies have the same status as car manufacturers, as Siemons confirms: “Our customer relationships here are comparable with those So what are U-UHP tires? we maintain in the original equipment sector,” he says. Ultra-ultra high performance tires are designed primarily to deal with very high speeds and loads. And UHP tires are also U-UHP tires in series production: the SportContact 6 defined by size. After all, the larger the wheel rim, the lower the sidewall of a tire and the greater its stability and resilience. U-UHP tire sizes range from 19 to 23 inches.. It can take up to three years to develop an ultra-ultra high performance tire. “We ensure we bring our best experts together for every tuning project so we can meet the most ambitious goals,” explains Krause. Achieving the knowledge transfer required to get the best results and ensure the devel-opment and application of new technologies invariably means sharing ideas and collaborating across departmental boundaries. 4 CASE STUDY ULTRA HIGH PERFORMANCE For example, while Black Chili technology has its origins in the development of bicycle tires, it is also used in high-tech car tires. This innovative new rubber compound lies at the heart of treads whose Micro Flexibility Compound ensures optimum interlock- ing between tire and road surface – making for outstanding grip in dry or wet conditions. Other technologies for cars designed to be pushed to the limits include the new Aralon 350 material component and Force Vectoring for the development of opti- mum tread structures (see box on page 11). In the new Continental SportContact 6, too, these technologies ensure for the first time that performance can be enhanced in all areas. “Normally, an increase in performance in one area will come at a cost elsewhere,” explains Krause. “There is a classic conflict between rolling resistance and braking performance, for example. In the SportContact 6, these conflicting interests have been overcome. This tire enhances dynamic performance while also maximising safety to an extent beyond any of our previous models,” sums up Siemons. Approved for speeds of up to 350 km/h, the SportContact 6 has the highest speed rating of any series-produced tire in the Continental portfolio. So it serves as the ideal basis on which to develop tires for the models that emerge from the workshops of the tuning firms. Tuning: a market with a big future Schnitzer AC Photo: Fast and heavy: Tuned SUVs, like the Range Rover by AC Schnitzer pictured here, present particularly stern challenges for tire developers. “Our aim in the tuning market is to provide the desired perfor- In addition to the high speeds these cars are capable of, the extra kilos they carry also need to be factored in. mance in impressive style and, in so doing, show that we have already got this sector well covered,” says Siemons. “The image The tuning market is heading for a lucrative future.

Young new-car CASE STUDY ULTRA HIGH PERFORMANCE 5 Highest safety rating for high speeds: The new Continental SportContact 6 Innovation leader and technology trailblazer Continental has laid down another significant marker in the tuning segment. Tuning aficionados unwilling to settle for second-best in the premium segment can now add the new SportContact 6 to their wish list. Steering precision is up by 14 percent over its predecessor (the ContiSportContact 5 P) and handling on dry surfaces shows an eleven percent improvement. Grip in track conditions is four percent better than before. And the new SportContact 6 raises the high bar set by its predecessor for overall performance in the wet by another two percent. In addition, mileage and ride comfort both see a seven percent improvement. Extreme performance and optimum safety at up to 350 km/h are the key attributes of the SportContact 6.

  • Michelin: Socially Responsible Industrial Restructuring (Research Report)
    Michelin: Socially Responsible Industrial Restructuring (Research Report) Professor Sandra J. Sucher and Research Associate Susan J. Winterberg* Introduction This report describes Michelin’s approach to socially responsible industrial restructuring.a The report was designed to serve two purposes—documentation and learning. The report provides documentation of Michelin’s practices in socially responsible industrial restructuring and contains an agreed upon description of Michelin’s planned, integrative, and humanistic approach. The report was also written as an opportunity for learning for Michelin’s leaders. The report traces the evolution in planning and practices that Michelin has used to conduct socially responsible restructuring over time. The resulting picture is both a view from the inside—told in the words and through the actions of Michelin’s managers—and a view from the outside—incorporating the reactions of stakeholders to Michelin’s restructuring approaches in various situations. Hopefully, it helps Michelin’s leaders assess where they have been and where they are headed in their evolving journey in socially responsible industrial restructuring.

  • Measuring Dynamic Properties of Bicycle Tires
    Proceedings, Bicycle and Motorcycle Dynamics 2010 Symposium on the Dynamics and Control of Single Track Vehicles, 20 - 22 October 2010, Delft, The Netherlands Measuring Dynamic Properties of Bicycle Tires A. E. Dressel *, A. Rahman # * Civil Engineering and Mechanics # Civil Engineering and Mechanics University of Wisconsin-Milwaukee University of Wisconsin-Milwaukee P.O. Box 784, Milwaukee, WI 53201-0784 P.O. Box 784, Milwaukee, WI 53201-0784 e-mail: [email protected] e-mail: [email protected] ABSTRACT Dynamic tire properties, specifically the forces and moments generated under different circum- stances, have been found to be important to motorcycle dynamics. A similar situation may be expected to exist for bicycles, but limited bicycle tire data and a lack of the tools necessary to measure it may contribute to its absence in bicycle dynamics analyses. This paper describes tools developed to measure these bicycle tire properties and presents some of the findings. Cornering stiffness, also known as sideslip and lateral slip stiffness, of either the front or rear tires, has been found to influence both the weave and wobble modes of motorcycles. Measuring this property requires holding the tire at a fixed orientation, camber and steer angles, with re- spect to the pavement and its direction of travel, and then measuring the lateral force generated as the tire rolls forward. Large, sophisticated, and expensive devices exist for measuring this characteristic of automobile tires. One device is known to exist for motorcycle tires, and it has been used at least once on bicycle tires, but the minimum load it can apply is approximately 200 pounds, nearly double the actual load carried by most bicycle tires.
